he then learns that by viewing the future, the future has viewed him and that the future was now locking into place. So Syz knows things are coming for him and that he has paid a terrible price already with more to come.

I like that philosophical assumption in the comic. It aligns with modern physics. Once a possible future is observed, all other possible futures collapse and only the observed one remains.

Yeah it is an interesting theory. Dr Who has used it a few times over the years.

Does seeing the future really lock it in?

In Beast Wars it was shown that Megatron had the Golden Disc from Voyager that contained pictures of Earth. He had a mountain destroyed and the picture of it in the future altered accordingly. Thus altering the present changes the future despite having future records of it.
